Metoprolol succinate is an extended-release version of metoprolol, so it remains in your bloodstream for a longer time. Metoprolol is a beta1-selective (cardioselective) adrenergic blocking agent. Metoprolol reduces production of c AMP from ATP, stimulated by katecholamines. It reduces the chronotrop, dromotrop and batmotrop activity and has a negative inotrop action on heart muscles. As a result of this mechanism the heart rate falls, the recovery time in sinus node increases as well as the refractory time in the atrioventricular node. This lead to atrial stimulation and prolongation of atrioventricular interval. These processes simultaneously stipulate the less cardiac output demand of oxygen, and, connected with these thereafter lessen the oxygen necessity. All of these mechanisms leads to antianginal effect. Sertraline 50 mg tab Diflucan generic brand Metoprolol belongs to a class of drugs known as beta blockers.
